PHILADELPHIA — Authorities say several men robbed a Philadelphia gas station, firing a shot that grazed the clerk. But it's what they did afterward that has police scratching their heads.
Police tell KYW-TV that instead of fleeing, the robbers stuck around early Monday and pumped gas, offering a discount to those who paid cash.
Lt. John Walker calls the robbers' actions "bizarre." He says they probably felt they didn't get enough money in the stickup "so they're going to sit there, take control of the business, offer gas at a discounted price and try to get additional money."
The clerk's father says his son was told by the robbers to stay in the bathroom for two hours. Police say the robbers are at large.
